    3434If you want to look for a specific pixel, you can select it by its position (lat,lon) or by its coordinates (x,y) on the flightline's grid. Note that the script with only accept (lat, lon) inputs within the range of latitude and longitude of the flightline to prevent human errors.

    36 Verbose mode is recommended when running this script and will print on screen information about the given pixel and the viewing angles needed to run the py6s model if the pixel is not a Nadir.

    3838This will plot the Fenix spectra against the at-sensor Py6S vegetation model. In this case, both figures will only match if the pixel given as input is a vegetation one and therefore, some caution is recomended when interpreting the plot.

    4141=== Ground Reflectance ===
    42 If an in-situ ground spectra has been measured and is available, you can run a more precisse Py6S model by giving its path. In this case, the ground reflectance will not be a vegetation type predefined by py6s and your reflectances values will be computed on the model.

    4343You will need to add -s when running the script:
    4444plot_fenix_vs_py6s.py -v -s ./GROUND_SPECTRA_PATH                                (-i -m. -n, --plot are still required)
